Onsite assessment of material waste minimization of operations on construction projects

Abstract

The minimization effectiveness of any framework can be determined by subjecting it to objective assessment on real-life projects before it can be engaged as a reliable tool for practitioners. This study is an objective validation of a framework for materials waste minimizations (FMWM) on construction sites. The specific objectives are to: refine the structure of the FMWM; assess the FMWM; evaluate its effectiveness; and determine implementation strategies of the FMWM. Cross-sectional survey and pure experimental research designs were used among professionals and construction projects in Lagos State. Data were collected using focus group discussions, interviews and site evaluation; and analyzed with descriptive and inferential statistical tools. The findings reveal that the FMWM is appropriate for material waste minimization with the overall effectiveness of 4.09%, which could be enhanced when the FMWM is used at all stages of construction projects. It implies that construction material waste can be reduced when the FMWM is adequately engaged. It is recommended that professionals should adopt the FMWM for site operations on their projects. This can be done by head offices mandating site teams to apply the FMWM on sites and requesting its inclusion on site reports.
